I don't know. There was a post in here earlier about the wiring, but I think that was for balanced.

I bought one from https://www.audiophileninja.com/product/ta-solitaire/ It doesn't have the threaded end, and the rough sleeve makes it transmit sound when rubbed against clothing, but it's good quality. That may not be what you're looking for.

There aren't any firmware updates yet, that I know of.

Right. Teams or any other call. Phone, zoom, whatever.

Fixed, as in, cannot be adjusted. It was too loud for calls for me (someone else mentions the same a couple pages back). They may fix this in firmware. The Solitaire sound stage is fine for me, but I preferred the Dali. I didn’t keep the Bathys for long, and I didn’t have them at the same time...

For the Solitaire, the size worked better for me. The ear pads of the Dali also made me hear my heartbeat very loud, which was distracting. There are Bluetooth calling issues with the Dali as well, see the thread (mic is bad, volume is fixed, etc.)

I've had (and returned) both. I greatly preferred the IO-12 in all aspects. Sound stage, clarity, comfort. If not for a few things I would have kept it. I ended up with the Solitaire T, but I think I preferred the sound of the IO-12 slightly.

Were you on a call? If I'm connected to multiple devices and on a call, I hear "Connected" every 30-60 seconds. I have to disconnect from the second device. I've reported this to T+A, and I'd encourage you to do the same.

Could someone with a Solitaire T and another Bluetooth over-ear headset please compare the microphone volume between those two headsets on an iPhone? You can use voice memo to record your voice. My ST mic seems to have very low volume (12 db lower) compared to my QC 35 II. I don't know if it was...

My guess was input/output given that they have a mic.

Thanks. I've got a used one coming tomorrow... I may very well have wasted some money on it, but we'll see. I'll be comparing it to an RME Babyface Pro FS, which supposedly has a very good DAC, but a lower powered amp (I know this likely doesn't matter since the ST are easy to drive).

I've had both. Never did it ever seem like the T+A had more bass or too much bass. If anything they felt lacking, but that's probably me being used to Bose. The larger drivers of the IO-12 could be felt more. Btw, IO-12 has more bass w/ ANC on. Turn it off to get less.

I've tried both. I kept the ST and I like the sound there in many songs, but I agree that in some it sounds a bit tin-can-like. I don't know what causes that. Something like the Daft Punk album doesn't have much oomph to it. I don't know how to explain it. But then I listen to some acoustic...

There is now an open box IO-12 on audio46.com. It’s probably mine since they just processed my return. They are basically perfect. None of the accessories/box were even touched and I didn’t even take the sticker off the side of the headphone. Hopefully one of you all can score it. Enjoy!

Interesting. Do you notice any audio quality improvements with the Mojo 2 at all? Or is it more or less the same as HQ mode?
